SLIDAB LE AND SWINGING WINDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 635,437, dated October 24, 1899. Application filedJ'une 22, 1899. Serial No. 721,472. (No model.)

To all whom it may concern.-

Beit known that I, BERNARD HAUSMANN, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Slidable and Swinging Window-Sashes; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a mechanism for sliding window-sashes and a means for disengaging such sashes, so that theyare turnable about hinges to swing inwardly for the purpose of obtaining access to the outside of the sash.

It consists of the parts and the constructions and combinations of parts which I will hereinafter describe and claim.

Figure 1 is a horizontal section of the window, showing the lower or inner sash partly opened aboutits hinges and the upper or outer one closed; also, theconstruction of partingstrip bet-ween both sashes, the grooves in inside and outside stops, and the slides. Fig. 2 is a perspective view of the hinged side, showing the construction and application of combined hinge -slide and locking device. Fig. 3 is a perspective view of the counterweight-slide upon the opposite side and the means for looking it when the sash is to be disengaged therefrom. Fig. 4. is a partial section showing the hook L and its stop.

A A are pulley-stiles.

B B are the upper and lower sashes, respectively, oneedge of each sash being hinged at one side, as will be hereinafter described, and the opposite edge closing against slides O, with which the counterweight-cord is con-' nected, so that when the detachable edge of the sash is interlocked with the slide the counterweight acts to balance a portion of the weight of the sash.

To swing the sash inwardly, it is necessary to lock the slide 0 to permit the detachment of the sash and to prevent the counterweight from drawing it to the top of the window after the sash has been disengaged therefrom. In order to lock the slide before the sash is disengaged from it, I have shown a plate D or like device fixed flush with the pulley-stile a short distance above the middle of the window-frame, having holes d made through it, as shown plainly in Fig. 3.

E is a stop and key having projections e, adapted to enter the holes 61. When the slide (J has been drawn so as to expose these holes, the projections e are pushed into the holes, the head E projecting above the upper end of the slide 0, so that when the window is raised the slide 0 is arrested at that point. By the momentum of lifting to the point of contact with the stop E the slide 0 is arrested and the sash is disengaged and unlocked from same and can be swung inwardly about its hinges.

The hinges are made, as plainly shown in Fig. 1, so that the joint F, about which the sash is turnable, stands outside the line of the window-stops Gr for the purpose of allowing the sash to swing clear of the stop and easing when opened. From this hinge-joint F the part H extends to and forms a part of the slide I, which is, as shown, of metal of about the same thickness as the part H of the hinge and is slidable in grooves or channels J, made, respectively, in the outer stop and inner stop of the -window frame and on one side of the parting-strip K. The other hingeplate H curves from the pivot-pin F over the part H, then extends parallel with it, thence being bent at right angles across the inner edge of the sash, as shown at H and is secured to thisedge of the sash by screws or other fastenings.

All the hinge and slide attachments except one in the lower sash are of the same construction. The one which dilfers is the lower hinge of the lower sash. Opposite this hinge I have shown a mortise made in the edge of the sash to receive the locking-hook L, and in this construction the part H of the hinge extends straight across the bottom of the mortise from the hinge-joint F instead of being bent parallel with the part H, as shown in the other hinges. This mortise forms a chamber for the locking-hook L to turn into.

When' unlatched from the slide 0, the sash is retained in place partly by the counterweight acting upon it on the hinged side and by the partin g-stri p and grooves in the inside and outside stops, which hold the sliding plate attached to the hinge and prevent its falling out.

The sash is held above the window-sill, when opened, by means of a fulcrumed hook L, which is so pivoted to the sliding plate that the upper end will drop by gravitation. This hook L is fulcrumed to the slide I, as shown, and when the sash is opened the upper part of this hook falls over against the channel or recess P in the pulley-stile and slides down with the movement of the sash until it reaches the stopping-plate, which arrests and holds the sash above the window-sill.

The parting-strip K is made with a groove or channel J along the outer side to receive the sliding plate I of the upper sash, and on the opposite or inner side it is formed with a lug or projection K, which forms a similar channel for the outer edge of the sliding plate I of the lower sash. The inner edge of this plate extends beyond the part II of the hingeplate and slides in a similar groove or channel J, made beneath the inner stop G.

\Vhen the sash is in its normal position, it is closed and latched against the slide C in any usual or suitable manner, and thus en gaged the sash and its couuterweighted slide move up and down in unison in the usual manner of such windows. In this condition the hook L is held in a vertical position and cannot engage the stop P or interfere with the sliding of the sash. \Vhen the sash is to be opened, it is down or is to be first drawn down to expose the holes 61 above the slide C, and the key E is inserted above the slide 0. The sash is then slightly raised, and when the slide G comes in contact with the key E any further slight lifting of the sash disengages its detachable edge from the slide and allows the sash to be opened about its hinges. By reason of the hinge-joint being set out as shown the sash immediately clears the casing and stops, and as it swings it releases the lug L, so that the hook L drops by gravitation into the channel I, moving down until it is arrested by plate or shoulder at the bottom, so that the sash then hangs just above the window-seat and is freely turnable about its hinges and can be opened inwardly. To open the upper sash, it is lowered to the sill and operated in like manner. 3y this construction it is necessary to cut away the sides of the window-sash and to insert slides of considerable thickness, which slides must project beyond the stops and parting-strip in order to allow the usual opening. It is only necessary to cut away mortise in the sash sufiicient to receive the hook L and the lugs in which it is journaled, while the plates I, being of comparatively thin metal, are screwed upon the edges of the sash, occupying but little space, and the grooves or channels J J, in which they slide, are equally narrow and easily formed without mutilation of the sash. The stop or key upon the opposite side being independent can only be used by the one having possession of it, and undesirable interferenee with the window is thus prevented.

The parts are also much less expensive, and the time necessary for fitting up a window with this device is very much lessened.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hinged sliding window, the metal plates fixed to the edges of the sashes, projeeting upon each side, stops and parting strips having grooves or channels and tongues in which said edges are adapted to slide, and hinge-plates projecting at right angles with said slides with the pivot-point exterior to the stops and parting-strips.

2. A hinged and slidable window having metal strips fixed to the inner edges of the sashes and projecting upon each side, slots formed in the stops and parting-strips, in which the projecting edges of said slides are guided and movable, one hinge-leaf projecting at right angles from the slide to a point beyond the line of the stops and partingstrips, the other leaf hinged thereto and fixed to the edge of the sash.

3. A hinged and sliding window having the combined sliding plates and hinges as shown, and a locking-hook pivoted with relation to the sash with the upperend adapted to tilt by gravitation and to engage a stop in the pulley-stile when the sash is open about its hinges, and a projecting lug to contact with the sash when it is closed, whereby the hook is thrown out of engagement with the stop and held in a vertical position in its chamber.

4. A combined hinge and slide for hinged sliding windows consisting of a plate having the edges projecting beyond the edges of the sash and slidable in slots or channels formed in the stops and parting-strip, and a projection at right angles with said plate having the hinge-joint beyond the line of the stops and parting-strip, and a similar plate fixed to the edge of the sash and pivoted to the projection of the sliding plate.

5. A hinged sliding window-sash, consisting of a sliding plate movable in guides in the window-easing, having a projection at right angles, a second plate hinged to the projection beyond the line of the stops and partingstrip, and secured to the edge of the sash, a mortise formed in the edge of the sash, lugs or plates turned at right angles with the sliding plate into the chamber of the sash, a hook pivoted between said lugs having its upper end adapted to tilt by gravitation so as to engage a stop in the pulley-stile, and a lug projecting from the hook-plate which by the closing of the sash disengages the hook.

In witness whereof I have hereunto set my hand.
